Greenfield Project
In many disciplines, a greenfield project is one that lacks constraints imposed by prior work. The analogy is to that of construction on greenfield land where there is no need to work within the constraints of existing buildings or infrastructure. Software development In software development, a greenfield project could be one of developing a system for a totally new environment, without concern for integrating with other systems, especially not legacy systems. Such projects are deemed higher risk, as they are often for new infrastructure, new customers, and even new owners. Thus, greenfield projects offer a unique opportunity to innovate freely and create from scratch. Cell phone networks In wireless engineering, a greenfield project could be that of rolling out a new generation of cell phone networks. The first cellular telephone networks were built primarily on tall existing tower structures or on high ground in an effort to cover as much territory as possible in as little ...

Greenfield Land
Greenfield land is a British English term referring to undeveloped land in an urban or rural area either used for agriculture or landscape design, or left to evolve naturally. These areas of land are usually agricultural or amenity properties being considered for urban development. Greenfield land can be unfenced open fields, urban lots or restricted closed properties. They are kept off limits to the general public by a private or government entity. Greenfield sites offer a high degree of freedom for a developer, compared to sites with existing developments. For example, a greenfield site is a welcome opportunity for a cable Cable may refer to: Mechanical * Nautical cable, an assembly of three or more ropes woven against the weave of the ropes, rendering it virtually waterproof * Wire rope, a type of rope that consists of several strands of metal wire laid into a hel ... operator to choose equipment based on cost and aesthetic parameters, without considering migration iss ...

Wireless Engineering
Wireless Engineering is the branch of engineering which addresses the design, application, and research of wireless communication systems and technologies. Overview Wireless engineering is an engineering subject dealing with engineering problems using wireless technology such as radio communications and radar, but it is more general than the conventional radio engineering. It may include using other techniques such as acoustic, infrared, and optical technologies. History Wireless technologies have skyrocketed since their late 19th Century advancements. With the invention of the FM radio in 1935, wireless communications have become a concentrated focus of both private and government sectors. In Education Auburn University's Samuel Ginn College of Engineering was the first in the United States to offer a formalized undergraduate degree in such a field. The program was initiated by Samuel Ginn, an Auburn Alumni, in 2001. Auburn University's college of engineering divides their wire ...

Base Station
Base station (or base radio station, BS) is – according to the International Telecommunication Union's (ITU) Radio Regulations (RR) – a " land station in the land mobile service." A base station is called '' node B'' in 3G, '' eNB'' in LTE ( 4G), and '' gNB'' in 5G. The term is used in the context of mobile telephony, wireless computer networking and other wireless communications and in land surveying. In surveying, it is a GPS receiver at a known position, while in wireless communications it is a transceiver connecting a number of other devices to one another and/or to a wider area. In mobile telephony, it provides the connection between mobile phones and the wider telephone network. In a computer network, it is a transceiver acting as a switch for computers in the network, possibly connecting them to a/another local area network and/or the Internet. In traditional wireless communications, it can refer to the hub of a dispatch fleet such as a taxi or delivery fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio Spectrum
The radio spectrum is the part of the electromagnetic spectrum with frequencies from 3 Hz to 3,000 GHz (3 THz). Electromagnetic waves in this frequency range, called radio waves, are widely used in modern technology, particularly in telecommunication. To prevent interference between different users, the generation and transmission of radio waves is strictly regulated by national laws, coordinated by an international body, the International Telecommunication Union (ITU). Different parts of the radio spectrum are allocated by the ITU for different radio transmission technologies and applications; some 40 radiocommunication services are defined in the ITU's Radio Regulations (RR). In some cases, parts of the radio spectrum are sold or licensed to operators of private radio transmission services (for example, cellular telephone operators or broadcast television stations). Ranges of allocated frequencies are often referred to by their provisioned use (for exampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WiMAX
Worldwide Interoperability for Microwave Access (WiMAX) is a family of wireless broadband communication standards based on the IEEE 802.16 set of standards, which provide physical layer (PHY) and media access control (MAC) options. The WiMAX Forum was formed in June 2001 to promote conformity and interoperability, including the definition of system profiles for commercial vendors. The forum describes WiMAX as "a standards-based technology enabling the delivery of last mile wireless broadband access as an alternative to cable and DSL". WiMAX was initially designed to provide 30 to 40 megabit-per-second data rates, with the 2011 update providing up to 1 Gbit/s for fixed stations. IEEE 802.16m or Wireless MAN-Advanced was a candidate for 4G, in competition with the LTE Advanced standard. WiMAX release 2.1, popularly branded as WiMAX 2+, is a backwards-compatible transition from previous WiMAX generations. It is compatible and interoperable with TD-LTE. Newer versions ...

Brownfield Land
Brownfield is previously-developed land that has been abandoned or underused, and which may carry pollution, or a risk of pollution, from industrial use. The specific definition of brownfield land varies and is decided by policy makers and land developers within different countries. The main difference in definitions of whether a piece of land is considered a brownfield or not depends on the presence or absence of pollution. Overall, brownfield land is a site previously developed for industrial or commercial purposes and thus requires further development before reuse. Examples of post industrial brownfield sites include abandoned factories, dry cleaning establishments, and gas stations. Typical contaminants include hydrocarbon spillages, solvents and pesticides, asbestos, and heavy metals like lead. Many contaminated post-industrial brownfield sites sit unused because the cleaning costs may be more than the land is worth after redevelopment. Previously unknown underground w ...

Brownfield (software Development)
Brownfield development is a term commonly used in the information technology industry to describe problem spaces needing the development and deployment of new software systems in the immediate presence of existing (legacy) software applications/systems. This implies that any new software architecture must take into account and coexist with live software already in situ. In contemporary civil engineering, brownfield land means a property, the expansion, redevelopment, or reuse of which may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant. Brownfield development adds a number of improvements to conventional software engineering practices. These traditionally assume a "clean sheet of paper", tabula rasa or "greenfield land" target environment throughout the design and implementation phases of software development. Brownfield extends such traditions by insisting that the context (local landscape) of the system being created be fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Greenfield Agreement
A Greenfield agreement is an agreement between a union and a new employer that does not yet have employees . This has a number of benefits for the . A key advantage is that a greenfield agreement does not require the approval of any employees whose would be subject to the agreement. Basically, there are no employees to negotiate with. Another key benefit is that a greenfield agreement provides an employer with the opportunity to shut out less desirable unions as parties and therefore effectively having a presence at ...
